i To all whom it may concern.

"hereby declare that the following is a full,

clear, and exact description of the invention,

such as will enable others skilled in the art. to which it appertains to make and use the same.

The present invention relates to improvements in storage buildings, having for its object to provide a cistern capable of successfully withstanding high winds or other stress which may be directed thereonto tend ing to cause weakening of the structure to Such an extent as topermit the cracking of the walls thereof of the deterioration of'said walls in any manner which will render the cistern leaky or unstable and "consequently,

unfit for use as a container for water.

It is also an object of the inventionto prolvide a cistern which is so constructed as to 25 5 above-freezing and yet not permit such wamaintain the water therein at a'temperat'ure ter to become warm or undesirable for drink.- ing purposes should it be desired for thi purpose. a

Other objects will be in part obvious and in part pointed out hereinafer; 5 i In order that the invention and the mode of its application may be readily understoodby workers skilled in the art, I have in the accompanying illustrative drawings and in the 'detalledfollowing descriptionbased thereon, set outone embodiment of the same. a

I In these drawings V P Figure 1 is a vertical section through the improved cistern;

Fig. 2 is a top plan view thereof;

Fig.3 is a fragmentary vertical section through the portion of the several walls of the structure;

Fig. at is a fragmentary tion through the same, and,

Fig. 5 is a fragmentary section through the pit of the cistern, taken on the line 5-5 of'th'e Fig. 1. r

Having more particular reference to the drawings in connection with which like reference characters will designate corresponding parts throughout the several views, the cistern comprehends a base or foundation preferab y formed f concrete or a mil r horizontal sec} Specification of Letters Patent.

material indicated at 1, said base being provided with a pit 2 whereby access may be posed fashion whereby to lend to therigidity of the walls, as clearly shown in the Fig. 3. These wires 7 may be arranged at any suitable distance apart such 'as will insure of proper bracing of the walls of the container 6. The upper portionof the container 7 is constricted or formed with an arch 8 of the same material as the walls thereof an opening being left therein to allow access to the interior thereof for various purposes and being normally closed by means of a cover 9 of corresponding size and' shape. The container 6 may be formed of brick, cement, tile or in fact, any material possessing the necessary rigidity and water retaining qualities. 7

As will be noted, therinner container 7 is arranged inwardly from the margin or peripheral edge of the annular-base 1, thus affording space suflicient to permit of the building of a housing 10 thereabout and to allow of the spacing of said housing 10 therefrom in order that a dead air space will be provided about the inner container, af-

fording an effective heat insulation there-- for, whereby to maintain the water in the same at a point above freezing buti yet prevent the same from reaching a tempera'ture thereof an opening is provided, which open ing is in alinement with the opening of the arch 9 and is normally closed by means of a cover 15 corresponding thereto in size, and shape. Also, the walls of the container 10 are provided with bracing wires 16 similar to the wires 7, but being arranged at greater distances apart, thus effectually bracing the same throughout. The walls of the housing 10 may be constructed of any suitable mater al Of e he rig d y necessa y to the practicability of the same, such for example as Wood, concrete, brick, tile, etc.

To brace the inner container and the housing 7 and 10 with respect to each other for the purpose of adding to the stability of the cistern in its entirety, I may and preferably do employ crossed oblique truss wires or cables 11, connecting the opposite ends of the same to the adjacent portions of the walls of said containers by looping the same as at 12 and embedding the same therein or otherwise connecting the same thereto, such as conditions or preference may-dictate. These trusswires 11, while serving to add to the rigidity of thecistern, .will notcpermit the conducting of vibration 7 from one container to the other, and in consequence, should the outer container be'subjected to any stress such as would cause vibration of the same, the detrimental effect thereof "will be confined to said outer eontainer alone and will not in any way effect the stability of the inner container 6. The

truss Wires 11 may be arrangedthrough the heights of the several containers, or if desired, may be confined to only the true perpendicular walls of thesame.

To prevent excessive filling of the container6, an overflow pipe 13 may be extended from the same at a suitable point thereonandobviously, will serve to conduct any excessive quantity of water therefrom.

. ceiving all stress to which the cistern may be subjected, as from wind storms or other detrimental elements. Vibration of the shield 10 will, as herein before stated, be prevented from being transmitted to the container 6, and therefore any liability of the cracking of such container of the breaking of portions therefore which would tend to render; it unfit for further use, will be avoided, allof which will be found to materially add to the practicability of the device in general.

lifanifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claims, I consider within the splrit of my invention.
